Product Overview
Features
Falco, fixed VOC gas monitor has an externally located Intrinsically Safe sensor for quick and easy servicing without the need for a hot work permit. Dual certification allows Falco to be serviced and calibrated in a hazardous environment without having to remove power!
The standard Falco fixed VOC gas monitor, both Pumped and Diffused models are supplied with a 10.6 eV lamp allowing the instrument to detect a wide range of VOC gases. The Falco fixed VOC gas monitor has 4 detection ranges available, these ranges include 0 – 10 ppm, 0 – 50 ppm, 0 – 1000 ppm and 0 – 3000 ppm.
The Falco TAC, both Pumped TAC and Diffused TAC models utilise a 10.0 eV lamp to detect Total Aromatic Compounds (TACs) which help focus on benzene. The Falco TAC is available with a detection range of 0 – 50 ppm.
